A java action can create a Hadoop configuration for interacting with acluster (e.g. launching a map-reduce job). Oozie prepares a Hadoopconfiguration file which includes the environments site configuration files(e.g. hdfs-site.xml, mapred-site.xml, etc) plus the properties addedto the sectionof the java action. The Hadoop configuration file is made available as alocal file to the Java application in its running directory. It can beadded to the java actions Hadoop configuration by referencing the systemproperty: oozie-action.conf.xml . For example:

If oozie.action.conf.xml is not added then the job will pick up themapred-default properties and this may result in unexpected behaviour. Forrepeated configuration properties later values override earlier ones."""
